Question

Find the angle, which is four times its supplement.
​

Answer 1

Answer:

144 DEG

Step-by-step explanation:

Let the angles be A and B

A+B=180

given A=4B

4B+B=180

5B=180

B=36

HENCE A=4(36)=144

Answer 2

Question

find the angle which is four times its supplement ?

Answer :-

Note :-

∆ supplement numbers added together to make the sum value to be 180 degree .like :- (90°+90°)=180° .

∆ complementary numbers added to make a some 90 degree like :- 60°+30°= 90°

Solution :-

180° - X = 360 - 4x

=> 180° = 360-4x+X

=> 180° = 360-5x

=> 5x = 360-180

=> 5x = 180

=> X = 180/5

=> X = 36

so to find 4x we have to multiply 36 with 4 .

=> 4(36) = 144

so the angle is 144 degree
